How can you tell if you have essential tremor or Parkinson s? One neurologist said essential tremor, a second said Parkinson s. I am going for another opinion, but would like to know how you distinguish one from the other. My hands do shake. Sometimes, at 6 AM or when I get up, I m trembling (but not cold). When I m more nervous, my hands do tremble more. I seem to be spilling or breaking things more. I will soon be 70 years old. I still hike, go to the gym and swim. Thanks for your help.
